While being guided by appropriate transport rollers 2 and 2, the molten zinc 3 is introduced into a plating tank 4 in which the molten zinc 3 is stored.
The steel sheet 1 with the molten zinc 3 adhered to the surface is taken out of the plating tank 4 by being turned back by the guide roller 5 provided therein. After taking out the plated steel sheet 1a, the zinc adhered to the surface is cooled and solidified, and then wound around a recoiler (not shown). Immediately before the steel sheet 1 comes out of the molten zinc 3, a pair of pressing rollers 6, 6 are provided, and the molten zinc 3 is pressed by both the pressing rollers 6, 6 so as to be printed on both sides of the steel sheet 1. 3 and the steel sheet 1 are improved in adhesion.

も出来る。In this way, in order to ensure that the load is supported by the first support block 22 and to prevent the rolling bearing 9 from being subjected to excessive stress, the upper surface of the first support block 22 should be formed as a middle convex surface. Instead of (or with the upper surface of the first support block 22 having a cylindrical convex surface), a support bracket fixed around the rolling bearing 9 as in the second embodiment shown in FIG. In the outer peripheral surface of the portion 14, the portion 18 located between the pair of outer ridges 17, 17 may be formed as a middle convex surface in which the axial middle portion is convex.

However, as a rolling bearing constituting the present invention, a ball bearing, a spherical roller bearing or the like can be used. In this case, if a spherical roller bearing is used as the rolling bearing, there is no need to incorporate an alignment mechanism between the support bracket 14 and the first and second support blocks 22 and 23.
That is, when a spherical roller bearing is used, the portion 18 between the outer ridges 17, 17 of the support bracket 14 is simply a cylindrical surface,
In addition, the upper surface or the side surface of the first and second support blocks 22 and 23 can be flat.
